ShowYou, a social video sharing tool that Apple called one of the top social-networking iPad apps of 2011, is letting its users go deeper.

First launched last April, ShowYou is sort of like Flipboard for video. Users see a grid of aggregated videos from sources like YouTube, Vimeo, and many others that have been shared by their friends on services like Twitter and Facebook.

Although the service is also available on the iPhone, its real value is on Apple's tablet, where users can easily scroll through an attractive grid of the latest and greatest videos making their way around the Internet. With both devices, users can also take advantage of Apple's AirPlay, so long as they have AppleTV 2.0.

Now, with version 3.0, ShowYou is letting users drill down into the social behaviors of their friends. The new version of the app, which launched this morning, users will be able to do a number of new actions including being able to zoom into friends' individual grids--meaning that you can see what other videos they've shared.

At the same time, the new version allows things like catching up on all videos shared in your social-network feeds; seeing what videos are hot according to popular hashtags; searching for videos by keyword; and browsing videos by specific category.

Although ShowYou, which is from San Francisco-based Remixation, won't say how many people have downloaded its apps, CEO Mark Hall touted their stickiness. Users spend an average of 35 to 40 minutes in the app per session, watching an average of eight videos each time. Hall said that because the new version offers greater depth than before, he expects sessions to last longer and for users to watch more videos than they have been until now.

He also said that by giving users better ways to dig into their friends' activities, Remixation expects the new version of ShowYou to attract a more mainstream community than its current early-adopter base.

Currently, Remixation is focusing its efforts on building ShowYou's user base and not on revenue, Hall said. The company received $2 million in series A funding from True Ventures. Eventually, the app may feature promoted videos.
